SHOE-SOLING MACHINE.

SPECIFICATION forming part of Letters Patent No.

' Application filed November 2l, 1882. (No model.)v

To all whom it may concern:

Beit known that I, JOHN WESTWOOD, of

Lynn, in the county of Essex and State of.

reference being had to th e accompanying dra-wings, forming part of this specification, in Which- 1 Figure 1 is a front elevation. Fig. 2 is a vertical section through the linea' xof Fig. l. Fig. 3 is a top View of the'soling-block J.

The object of my invention is to provide a machine for fastening the sole to the shoe by means of nails, which machine shall mold the sole, lay it, hold the nails, drive all the nails at once, guide the nail-drivers straight, and beat out the shoe to a uniform edge and smooth bottom, all in one operation.

To these ends my invention consists in the peeuliarconstruction andarrangemen'tof parts, as will be hereinafter fully described.

ln the drawings, A represents the main frame of the machine, which is preferably made of iron, but may be made of wood,if desired. The upper portion of this frame is provided with a table-surface, which is at each end perforated to receive the slide-rods B B of a vertically-reciprocatin g frame, which frame is formed by said slide'rods and the upper and lower cross-bars, C C', connecting the ends of the same. This frame is guided for true vertical reciprocation by the perforations in the table, and also by perforated lugs a a in the lower part of theframe-work, through which its side rods pass. This frame is held up by spiral springs b b, and is brought down with sufficient power to perform the required work of nailing the sole to the shoe by a treadle and compound-toggle mechanism.

D is the treadle, which is jointed to lugs about the middle ofthe lower cross-bar, G, and

at its back end is jointed to the lower end of a link-rod, E, which at its upper end isjointed to the middle joint of two toggle-arms, F F, which give a horizontal thrust. VOf these two toggle-arms the back one, F', is jointed at its rear Yend to a fixed horizontal bar, Gr, of the frame-work,and the front one, F, is jointed to 273,207, dated February 27, 1883.

the middle joint of another pair of togglearms, H H, which give a vertical thrust. The lower one of the second set Yof toggle-arms is jointed to Vthe lower cross-bar, C', of the reciprocating frame by means of the same bolt, c. that fastens the-treadle thereto, while the Lipper toggle-arm, H, is at its upper end jointed to the bottom of the table. Now, to bring down the reciprocating frame, it will be seen that a pressure on the treadie not only gives a direct downward pressure on the reciprocatingframe, but in straightening out the two sets of toggle-arms F F and H H it gives a compound movementof great leverage, which has greatest power at the last part of the stroke, or just when the greatest resistance is metwith in fastening on the sole and the greatest power is required.

To the upper cross-bar, C, of the reciprocating frame are adjustably attached the shoesoling devices proper, which act upon the shoe, which is supported upon an iron foot, l. These shoe-soling devices consist of a metal block, J, corresponding in contour to the sole of the foot, and a metal block, K, of a corresponding shape, which latter has two stems, d d, that pass through holes in the upper block and loosely connect it thereto and guide it for up-and-'down movement. The upper block, J, is the nail-driver, and it carries ou its lower side a series of studse e, projecting downwardly, and arranged near the edge of the block and in a position corresponding to the row of nails to he driven around the sole ofthe shoe. The lower metal'block is provided with a series of marginal holes corresponding exactly to the studs above and immediately beneath the same, and on its under side it is concaved or curved to correspond with the curve which it is desired to give the sole at the ball and shank. \'lhis block molds and lays the sole, forms the nail-guide, and beats the shoe out into proper shape on its bottom and edges.

The operation of these parts is as follows: The shoe having been lasted, or the upper tacked over the insole in the usual way, it is put on the iron foot, the sole placed on the same, andthe lower block, K, is brought down thereupon, and as there are two points, f, in the bottom face of the block K, these perform the work of laying the sole or punctnring and fixing it in proper position upon the other parts ofthe shoe. Nails are then dropped by hand in the row of perforations in the lower block, and then as the cross-bar and block J come down by the action of the treadle the nail drivers or studs e enter the holes in the lower block and force the nails into the sole ofthe shoe, and through it and the upper, and clinch against the iron foot below. Then as the pressure is continued the face of the upper block, J, strikes the face ot' the lower block, K, and by pressing the latter against the face ofthe sole the curve of block K is made to give the proper curve to the face ot' the sole and to beat or atten thersole to uniform surface and even edge.

To facilitate the work of fastening on the soles, a reversible bar, L, is pivoted to turn ,horizontally about one. of the vertically-sliding rods, and is made to support the iron feet in a detachable manner by means of two pegs ordowel-pins,gg, thatenter holesin the bottoms ofthe feet. 0n one end of this board is arranged one foot, upon which the right shoe is fitted, and on the other end of the board is the other foot, upon which the left shoe is fitted, the sole being connected to one shoe while the other shoe is being fitted on the other foot,

one end than the other, and its feet are so arranged that when one is swung around, it comes under the right set of soling devices J K, and when the other end is swung` around, the left foot is swung under the left soling devices connected to the cross-bar. The soling devices J K are to be made in varying sizes, and are readily attached to and detached from the cross-bar by means of their slots and keys.

For limiting the downward movement ot' the sole-driving studs, according asthe shoe is a single or double solcd shoe, the upper cross-bar may be adjusted down on the vertical rods by nuts fi, working on the threaded stems of said rods, the cross-bar being prevented from falling down by spiral springs j.

Having thus described my invention, what I claim as new is l. .The combination, with the reciprocating frame C C B B, carryingduplicate, nail-driving devices J K, one for the right foot and the other for the left, of the bar L, pivoted about one ofthe rods B, and bearinglasts I, arranged at different distances from the pivotal center to adapt them to be brought alternately un-v der the two sepatate nail-driving devices, as described.

2'. The combination ofthe main frame A, the reciprocating frame B B C U', lugs a, springs b b, the treadle mechanism, the nail-driving mechanism, and the removable iron foot, substantially as and for the purpose described.
